3 Claims.

This invention relates to a guard designed for use in connection with sliding window sashes, the primary object of the invention being to provide a guard which may be readily and easily applied to the upper bar of the lower window sash of a window, to close the opening between the upper and lower sashes caused by the movement of either sash to its open position.

An important object of the invention is to provide a guard of this character constructed preferably of sheet metal material of a yieldable character, so that a close fit between the sashes will be insured at all times.

A further object of the invention is to provide a guard embodying telescoping sections which may be adjusted to adapt the guard for use in connection with sashes of various widths.

With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may be made Referring to the drawing in detail, the reference character 5 designates the lower sash of a window, and the reference character 6 designates the upper sash thereof.

The guard forming the essence of the invention is indicated generally by the reference character I, and embodies a main section 8 constructed of a length of sheet metal material, bent upon itself to provide upper and lower sections 9 and I respectively.

As clearly shown by Figure 2 of the drawing,

the upper section 9 is longer than the lower section I0, so that it will extend to a point to engage a the inner surface of the window pane of the upper sash section, the lower section being curved downwardly as at H to contact with the outer surface of the upper bar of the lower sash of the window, setting up a binding action to secure the guardin position by frictional contact with the upper bar of the lower sash and the pane of the upper sash of the window.

The main section 8 is cut away as at l2 to provide a clearance for the central vertical bar of the window, as shown by Figure 1. The rear edge of the main section is also cut away at 13 so that the guard may be readily fitted around the usual window lock, which in the present showing is indicated at M.

The main section 8 is of a length so that when it has been positioned on a window sash, the ends thereof will be spaced appreciable distances from the side bars of the sash. Slidably mounted within the ends of the main section, and disposed between the upper and lower sections 9 and Ill thereof, are adjustable end pieces l5, the end pieces l being constructed to conform to the shape of the main section 8, so that the end pieces may slide between the upper and lower sections 9 and ID of the main section, permitting of adjustment of the end pieces with respect tothe main section, to close the spaces between the ends of the main section of the guard and the side bars of the sashes, with which the guard is used. Thus it will be seen that due to this construction, the end pieces may be moved longitudinally of the main section, adjusting the guard for use in connection with windows of various widths.

The main section 8, as well as the end pieces l5, are formed with tubular portions It, the tubular portions of the end pieces fitting in the tubular portion of the main section 8, securing the end pieces against displacement.

It might be further stated that the downwardly curved portions I l of the main section and end pieces, are curved slightly outwardly, to lend resiliency to the structure to insure a close fit between the sashes. 1

From the foregoing it will be seen that due to the construction shown and described, I have provided a guard which may be readily and easily positioned on the upper bar of the lower window sash, when either sash is moved to its open position, closing the space between the upper and lower bars of adjacent sashes, and preventing insects such as flies, mosquitoes or the like, from entering the room, through the space between the sashes.

What is claimed is:

1. A guard adapted for positioning on the upper bar of the lower sash of a window, comprising a main section embodying upper and lower sections, end pieces adjustably held within the ends of the main section and slidable between the upper and lower sections thereof, one front edge of the upper section being curved upwardly frictionally engaging the pane of the upper sash of the window with which the guard is used, and the front edge of the lower section being curved downwardly frictionally engaging the lower sash of the window, securing the guard in position.

2. A guard adapted for positioning on the upper bar of the lower sash of a window, comprising a main section constructed of a length of sheet metal material, said main section embodying upper and lower sections, the upper section being longer than the lower section, endpieces slidably held between the upper and lower sections of the main section, said end pieces embodying upper and lower sections, one edge of the upper section adapted to engage the pane of the upper window sash, the free edge of the lower section of the guard adapted to engage the upper bar of the lower window sash, securing the guard in position by frictional contact with the windows.

3. A guard adapted for positioning on the upper bar of the lower sash of a window, comprising a main section embodying upper and lower sections, end pieces slidably mounted between the upper and lower sections of the main section, the free edge of the upper section frictionally engaging the pane of the upper sash, the free edge of the lower section frictionally engaging the upper bar of the lower sash, holding the guard in position.
